(E)xtract (T)ransform (L)oad ToolsE – involves tools for extracting

the data from source systems (silos).

T – involves converting (transforming) the data into standardized formats.

L – involves loading & integrating data into a system (such as a data warehouse).

Disparate Data – Risks and IssuesResponsiveness requires intelligence

which requires trusted data & reporting systems.

Silos arise creating decisions based upon inaccurate, incomplete, possibly outdated data.

* Data that are too late* Data that are wrong level of detail-too much or too little* Directionless data* Unable to coordinate with departments across enterprise* Unable to share data in a timely manner

Business Intelligence Technologies1990s primarily associated with back

office workers & operations such as accounting, finance & human resources.

2000s expanded to enterprise data to include needs of managers & executives.

Vendors offered advanced analytic, decision support, easy-to-use interfaces, & improved data visualization tools. Web-based delivery became common-place.

Evolved from reporting to predicting.

BI Architecture Component 1 - Data Extraction & IntegrationMany sources such as OLAP, ERP,

CRM, SCM, legacy & local data stores, the Web all lacking standardization & consistency.

ETL (Extract-Transform-Load) tools provide data for analyses to support business processes.

Central data repository with data security & administrative tools for information infrastructure.

Page 14: Seminar 7 – Part 2 Business Intelligence and Decision Support Systems Ref: Chapter 12 – Turban and Volonino Seminar 7 – Part 2 Business Intelligence and

BI Architecture Component 2 - Enterprise Reporting SystemsProvide standard, ad hoc, or

custom reports.95% of Fortune 500 rely on BI to

access information & reports they need.

Reduces data latency.Decreases time users must

spend collecting the data; increases time spent on analyzing data for better decision-making.

Page 15: Seminar 7 – Part 2 Business Intelligence and Decision Support Systems Ref: Chapter 12 – Turban and Volonino Seminar 7 – Part 2 Business Intelligence and

Dashboards & ScorecardsDashboards are typically

operation & tactical in application & use.

Scorecard users are executive, manager, staff strategic level in application & use.

Multidimensional view of sales revenue data

Page 17: Seminar 7 – Part 2 Business Intelligence and Decision Support Systems Ref: Chapter 12 – Turban and Volonino Seminar 7 – Part 2 Business Intelligence and

BI Architecture Component 3 - Business Performance ManagementRequires methods to quickly &

easily determine performance versus goals, objectives & alignment strategies.

Relies on BI analysis reporting, queries, dashboards & scorecards.

Objective is strategic – to optimize overall performance of an organization.

Page 18: Seminar 7 – Part 2 Business Intelligence and Decision Support Systems Ref: Chapter 12 – Turban and Volonino Seminar 7 – Part 2 Business Intelligence and

Text-MiningContent that is mined include

unstructured data from documents, text from email messages & log data from Internet browsing.

May be major source of competitive advantage.

Needs to be codified with XML & extracted to apply predictive data mining tools to generate real value.

Comprises up to 80% of all information collected.

Page 19: Seminar 7 – Part 2 Business Intelligence and Decision Support Systems Ref: Chapter 12 – Turban and Volonino Seminar 7 – Part 2 Business Intelligence and

Advantages & Disadvantages of Data MiningTools that are interactive, visual,

understandable, & work directly on data warehouse of organization.

Simpler tools used by front line workers for immediate & long-term business benefits.

Techniques may be too sophisticated or require extensive knowledge & training.

May require expert statistician to utilize effectively, if at all.

Managers and the Decision Making

Process

Page 21: Seminar 7 – Part 2 Business Intelligence and Decision Support Systems Ref: Chapter 12 – Turban and Volonino Seminar 7 – Part 2 Business Intelligence and

Managers Need IT Support from DSS ToolsScenarios, alternatives & risks

are many.Time is always critical

consideration & stress level is high.

Require sophisticated analysis.Geographically dispersed

decision makers with collaboration required.

Often requires reliable forecasting.

Page 22: Seminar 7 – Part 2 Business Intelligence and Decision Support Systems Ref: Chapter 12 – Turban and Volonino Seminar 7 – Part 2 Business Intelligence and

Automating Manager’s JobRoutine decisions by mid-level

managers (frontline employees) may be automated fairly easily & frequently.

Automation of routine decisions leaves more time for supervising, training & motivating nonmanagers.

Top level managerial decision making is seldom routine & very difficult to automate.

Page 23: Seminar 7 – Part 2 Business Intelligence and Decision Support Systems Ref: Chapter 12 – Turban and Volonino Seminar 7 – Part 2 Business Intelligence and

IT Available to Support Managers (MSS)DSS - indirect support – discovery,

communication & collaboration with web facilitation.

DSS – provide support primarily to analytical, quantitative types of decisions.

E(xecutive)SS – early BI – supports informational roles of executives.

G(roup)DSS – supports managers & staff working in groups, remotely or closely.

Common devices – PDAs, Blackberrys, iPhones.

IT support for Decision Making

Page 25: Seminar 7 – Part 2 Business Intelligence and Decision Support Systems Ref: Chapter 12 – Turban and Volonino Seminar 7 – Part 2 Business Intelligence and

Phases in the decision-making process

Page 26: Seminar 7 – Part 2 Business Intelligence and Decision Support Systems Ref: Chapter 12 – Turban and Volonino Seminar 7 – Part 2 Business Intelligence and

Decision Modeling & ModelsDecision model – simplified

representation, or abstraction of reality.

Simplicity is key.Based upon set of assumptions.Requires monitoring & adjustment

periodically as assumptions change.Modeling – virtual experiments reduce

cost, compress time, manipulate variables, reduces risk.

Page 27: Seminar 7 – Part 2 Business Intelligence and Decision Support Systems Ref: Chapter 12 – Turban and Volonino Seminar 7 – Part 2 Business Intelligence and

Framework for Computerized Decision AnalysisStructured – routine & repetitive

problems.Unstructured – lots of

uncertainty, no definitive or clear-cut solutions.

Semistructured – between the extremes. Most true DSS are focused here.

Page 28: Seminar 7 – Part 2 Business Intelligence and Decision Support Systems Ref: Chapter 12 – Turban and Volonino Seminar 7 – Part 2 Business Intelligence and

DSS & ManagersNeed new & accurate

information.Time is critical.Complex organization for

tracking.Unstable environment.Increasing competition.Existing systems could not

support operational requirements.

Page 29: Seminar 7 – Part 2 Business Intelligence and Decision Support Systems Ref: Chapter 12 – Turban and Volonino Seminar 7 – Part 2 Business Intelligence and

Characteristics & Capabilities - DSSSensitivity analysis for “what if”

& goal-seeking strategy setting. Increases system flexibility & usefulness.

Basic components – database, model base, user interface, users & knowledge base.

ADS (Automated Decision Support)Rule-based systems with

automatic solutions to repetitive managerial problems.

Closely related to business analytics.

Automating the decision-making process is usually achieved by capturing manager’s expertise.

Rules may be part of expert systems or other intelligent systems.

Page 31: Seminar 7 – Part 2 Business Intelligence and Decision Support Systems Ref: Chapter 12 – Turban and Volonino Seminar 7 – Part 2 Business Intelligence and

Characteristics & Benefits of ADSRapidly builds business rules to

automate or guide decision makers, & deploys them into almost any operating environment.

Injects predictive analytics into rule-based applications, increasing their power & value.

Combines business rules, predictive models & optimization strategies flexibly into enterprise applications.

Page 32: Seminar 7 – Part 2 Business Intelligence and Decision Support Systems Ref: Chapter 12 – Turban and Volonino Seminar 7 – Part 2 Business Intelligence and

ADS Applications - Examples

Customizing products & services for customers

Revenue yield management

Uses filtering for handling & prioritizing claims effectively

Page 33: Seminar 7 – Part 2 Business Intelligence and Decision Support Systems Ref: Chapter 12 – Turban and Volonino Seminar 7 – Part 2 Business Intelligence and

Managerial Issues - Why BI Projects FailFailure to recognize as

enterprise-wide business initiatives.

Lack of sponsorship.Lack of cooperation.Lack of qualified & available

staff.No appreciation of negative

impact on business profitability.Too much reliance on vendors.
